Just a reminders, with Katou back there are now 11 hunters (well, 10 + the panda).
If anybody looked back to the first volume of gantz, they'd notice that gantz's rear rack only has 7 selves for power suits. Even if we asume that each shelf holds two cases, that means theres only room for 14 hunters at one time, unless you want them to run around without a suit. So theres really only 3 slots remaining for revivals.

\"However,\" replied the universe, \"The fact has not created in me a sense of obligation.\"
